Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F6810CS are classified based on electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters (Must Match):

• Resistance value: 681 Ohms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Terminations: 2
• RoHS3 Compliance

Allowable Variations:

• Power rating: 0.063W (1/16W) or higher (0.1W / 1/10W)
• Features: Moisture Resistant designation or Automotive AEC-Q200 certification
• Manufacturer: Different manufacturers with identical electrical specifications

Substitution Categories:

Direct Equivalents maintain all electrical and mechanical parameters identical to the main part:

• CR0402-FX-6810GLF (Bourns Inc.)
• RC0402FR-07681RL (YAGEO)

Upgrade Option provides higher power rating while maintaining all other specifications:

• ERJ-2RKF6810X (Panasonic Electronic Components) — 0.1W / 1/10W rating with Automotive AEC-Q200

Similar Options include automotive-grade certification or enhanced moisture resistance:

• AC0402FR-07681RL (YAGEO) — Automotive AEC-Q200 + Moisture Resistant
• CRCW0402681RFKED (Vishay Dale) — Automotive AEC-Q200
• RMCF0402FT681R (Stackpole Electronics Inc) — Automotive AEC-Q200

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Consumer/Industrial Applications): CR0402-FX-6810GLF and RC0402FR-07681RL are functionally equivalent to RC1005F6810CS. Both maintain identical electrical specifications, package dimensions, and RoHS3 compliance. Selection between these options depends on supplier availability and inventory status.

For Automotive Applications: AC0402FR-07681RL, CRCW0402681RFKED, and RMCF0402FT681R incorporate Automotive AEC-Q200 certification, qualifying them for automotive-grade circuit designs. These parts maintain the 0.063W power rating and all electrical parameters of the original specification.

For Power Margin Applications: ERJ-2RKF6810X provides a 0.1W (1/10W) power rating, offering increased thermal headroom compared to the 0.063W (1/16W) specification of RC1005F6810CS. This upgrade option includes Automotive AEC-Q200 certification and is suitable for applications requiring enhanced power dissipation capability within the same package footprint.

Compliance Considerations: All substitute parts maintain RoHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and identical operating temperature ranges (-55°C ~ 155°C). No additional qualification or testing is required based on regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-6810GLF replace RC1005F6810CS in any application? A: CR0402-FX-6810GLF is a direct electrical and mechanical equivalent. Both parts share identical resistance (681 Ω), tolerance (±1%), power rating (0.063W), package (0402), and operating temperature range (-55°C ~ 155°C). Substitution is valid for all applications where RC1005F6810CS is specified, subject to supplier availability.

Q: What is the difference between the 0.063W and 0.1W power ratings? A: Power rating indicates the maximum continuous power dissipation capability. ERJ-2RKF6810X (0.1W) can dissipate more heat than RC1005F6810CS (0.063W) while maintaining the same physical package size. For applications operating below 0.063W, both ratings are functionally equivalent. For applications approaching or exceeding 0.063W dissipation, the 0.1W option provides additional thermal margin.

Q: Are automotive-grade parts (AEC-Q200) suitable for non-automotive applications? A: Automotive AEC-Q200 certified parts meet stringent reliability and quality standards that exceed general industrial requirements. These parts are fully compatible with non-automotive applications and provide enhanced reliability margins. No design modifications are required when substituting automotive-grade parts into consumer or industrial circuits.

Q: Does the Moisture Resistant feature affect substitution compatibility? A: Moisture Resistant designation indicates enhanced protection against moisture ingress. RC1005F6810CS and RC0402FR-07681RL both include this feature. Parts without explicit Moisture Resistant designation (CR0402-FX-6810GLF) maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity limitations. Substitution between moisture-resistant and non-moisture-resistant variants is electrically valid; selection depends on environmental exposure requirements.

Q: Can these 0402 package parts be used interchangeably on the same PCB? A: All substitute parts share identical 0402 (1005 Metric) package dimensions: 0.039" L × 0.020" W (1.00mm × 0.50mm). Maximum seated height varies slightly (0.015" to 0.016"), remaining within standard PCB assembly tolerances. Parts are mechanically interchangeable on standard 0402 footprints without PCB redesign.

Q: What inventory levels are available for each substitute part? A: Current inventory status: RC1005F6810CS (1,120 pcs), CR0402-FX-6810GLF (44,103 pcs), RC0402FR-07681RL (15,240 pcs), ERJ-2RKF6810X (64,750 pcs), AC0402FR-07681RL (11,091 pcs), CRCW0402681RFKED (18,299 pcs), RMCF0402FT681R (99,034 pcs). Inventory levels support high-volume procurement requirements across all substitute options.

Q: Are all parts REACH compliant? A: All listed parts maintain REACH Unaffected status, indicating full compliance with REACH regulations. No additional documentation or qualification is required for REACH compliance when substituting between any of these parts.
